Hmm. If a fix is possible that doesn't actually show to users, it's probably best for a plain bug fix, though it should probably be okayed by a staff someone. Stuff that would noticably change how stuff looks (other than fixing this thing) probably does need to go through suggestions.

Poking the internet about it, it looks like the max-height thing is basically the only fix, and browser targeting tends to not really work (other than whacky IE-related stuff, anyway) - but if the height is sufficiently large, it should look the same to other users. Google seems to be of the opinion that it's working as intended.
